ACOUSTIC FEEDBACK Meaning and
Definition
-
Acoustic feedback refers to a phenomenon that occurs in audio systems when sound from a speaker is captured by a microphone and then amplified, resulting in a continuous loop of sound that grows louder and more intense. This loop is commonly known as feedback or the Larsen effect.
Acoustic feedback occurs due to the sound waves emitted by the loudspeaker being picked up by the microphone and then re-amplified. When this sound is re-amplified and played back through the speaker again, it is picked up by the microphone once more, creating a never-ending cycle or loop of sound. As the feedback loop continues, the sound level increases, potentially reaching a point where it becomes uncontrolled and produces a high-pitched squeal or screech.
Typically, acoustic feedback is unwanted and considered a technical flaw, particularly in live sound setups or recording environments. It can interfere with the clarity and quality of the sound reproduction, making it difficult for performers or users to discern or interpret audio cues accurately.
To minimize or eliminate acoustic feedback, various techniques are employed. These include adjusting the positioning of loudspeakers and microphones, utilizing directional microphones with tight pickup patterns, adding acoustic treatments to the room, or employing anti-feedback devices that actively detect and counteract the feedback frequency. By addressing the causes of acoustic feedback, sound engineers and technicians can create a more controlled and optimal audio experience.

Etymology of ACOUSTIC FEEDBACK
The etymology of the word "acoustic feedback" can be broken down as follows:
1. Acoustic: The term "acoustic" comes from the Greek word "akoustikos", meaning "pertaining to hearing or sound". It gained prominence in English during the mid-17th century.
2. Feedback: The word "feedback" originated in the field of electronics. It was first used in the 1920s to describe a process where a portion of the output of a device is redirected back to the input, allowing for self-regulation and control of the system. The term was later extended to various fields, including audio and sound technology.
When these two terms are combined, "acoustic feedback" refers to sound energy being looped back into an audio system, creating a high-pitched squealing or howling sound.
